用途：MO-200氧氣測量儀可(ke)用(yong)于室(shi)內(nei)氧(yang)(yang)(yang)(yang)氣(qi)(qi)測量，氣(qi)(qi)候(hou)室(shi)氧(yang)(yang)(yang)(yang)氣(qi)(qi)監測，堆肥、尾礦(kuang)氧(yang)(yang)(yang)(yang)氣(qi)(qi)監測，監測土壤(rang)(rang)氧(yang)(yang)(yang)(yang)化還原電(dian)(dian)(dian)(dian)位(wei)，以及(ji)在密閉空間中監測土壤(rang)(rang)呼吸速率和土壤(rang)(rang)呼吸耗(hao)(hao)氧(yang)(yang)(yang)(yang)量，還可(ke)監測管線氧(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)(nong)度，MO200氧(yang)(yang)(yang)(yang)氣(qi)(qi)測量儀由讀(du)數(shu)表(biao)和傳(chuan)(chuan)感器(qi)組成。電(dian)(dian)(dian)(dian)流(liu)型的氧(yang)(yang)(yang)(yang)氣(qi)(qi)傳(chuan)(chuan)感器(qi)包含一個(ge)(ge)鉛正極、金(jin)負(fu)極、電(dian)(dian)(dian)(dian)解(jie)液和一個(ge)(ge)Teflon膜。電(dian)(dian)(dian)(dian)極間的電(dian)(dian)(dian)(dian)流(liu)與測量得到的氧(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)(nong)度程正比，一個(ge)(ge)內(nei)置的橋(qiao)式電(dian)(dian)(dian)(dian)阻用(yong)于提供電(dian)(dian)(dian)(dian)壓(ya)(ya)輸(shu)出(chu)。作為電(dian)(dian)(dian)(dian)流(liu)型傳(chuan)(chuan)感器(qi)，需要消耗(hao)(hao)少量氧(yang)(yang)(yang)(yang)氣(qi)(qi)以產生響(xiang)應的電(dian)(dian)(dian)(dian)壓(ya)(ya)信(xin)號。當氧(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)(nong)度是(shi)20.95% (3240 mmol，23℃) 的時候(hou)，測量得到的氧(yang)(yang)(yang)(yang)氣(qi)(qi)消耗(hao)(hao)是(shi)2.2 umol O2/天。電(dian)(dian)(dian)(dian)壓(ya)(ya)信(xin)號輸(shu)出(chu)響(xiang)應于空氣(qi)(qi)氧(yang)(yang)(yang)(yang)氣(qi)(qi)分壓(ya)(ya)，分壓(ya)(ya)標準單位(wei)是(shi)kPa，這些(xie)單位(wei)可(ke)以轉換為%O2或ppm，大氣(qi)(qi)中的氧(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)(nong)度是(shi)大約20.95%。

MO-200氧氣測量儀特點：        

傳感(gan)器配備加(jia)熱(re)檢(jian)測(ce)器，傳感(gan)器的(de)(de)前面的(de)(de)保護膜可以被加(jia)熱(re)，當(dang)傳感(gan)器在土壤或堆(dui)肥時可以防止(zhi)水凝結阻(zu)擋擴散(san)路徑。        

堅固的傳感器外殼，即(ji)使(shi)酸性(xing)環境下也可(ke)使(shi)用，A0-001可(ke)用于(yu)擴散(san)式測(ce)量(liang)，A0-002可(ke)用于(yu)管線式測(ce)量(liang)。每(mei)個(ge)氧氣傳感器都(dou)內置一個(ge)溫(wen)度傳感器，可(ke)實現溫(wen)度的監測(ce)和(he)，信號校(xiao)正
